Everything about Engine Valves

This is a ridiculous amount of chat about engine valves and explains all their components, covering valve guides, faces, and the valve seats. We also touch on the two main faults that you might encounter with valves - bent or burnt.
As always:
No adverts.
No clickbait titles.
No fake thumbnails with pictures of stuff that isn't even in the video
No hustling for you to subscribe.
...Just straight up information
... and if you like it you'll probably like the video course that it comes from at www.howacarworks.com/video-course
This valve gear is from a 2001 Mazda MX5 Miata.

DO NOT PAY FOR THIS! it may not have started as a scam but now it is for sure! if you check social media, you will find a lot of people who ask for help and were ignored by this guy. in a few weeks the site forgot I bought the course and even if I am loged it it won't let me watch videos, offering me instead to buy the course again. no one responds emails nor messages sent to the social media profiles. also, the course is incomplete and this guy has not uploaded anything in years. and none of the site-only videos were is 4k as promised. only the free youtube ones were. there is not even an option to download the videos, so unless you know of a hackey way to do so, don't bother giving money for this. if someone finds a way to download the videos, please upload them to the pirate bay. despite all, the videos were actually quite good.

A well done video. What's really annoying about interference engines is when they put rubber timing belts on them. Then when the break, you lose the engine because you didn't change out a $50 belt. This is why I'm glad that for the most part, a few good auto makers (Toyota, Ford and others) make non-interference engines with timing chains, or at least chains when they are interference engines.

Got a 2014 Chevy Silverado that blew its engine back in October, 180k miles, and finally figured out last week a valve went out in the engine and apparently parts of the valve were found in the exhaust. When it went out on me it still drove for about a mile as I could safely get off the road if I didn’t stop immediately so I had that going for me as well as we were able to find an engine to replace it with. Decided to look more into valves and this video was interesting. Hopefully how I said that makes sense, I heard what caused it from my dad who is in contact with the guy that’s replacing the engine for us so I haven’t seen any of this myself.

Great video! I have a question regarding valve float: does the ignition process in the combustion chamber provide any force that aids the spring in closing the valve stem and keeping it in contact with the follower? I'm doing some analysis on a cam-follower and valve-stem assembly, and it seems that the force needed to keep the valve in contact with the follower is extremely high (~10,000 lbf or ~44,000 N of force) much higher than is reasonable with springs that would fit in that area. Do you or any other viewers here have ideas or input on this?

Very cool. I know as much about engines as a box turtle knows about The Who; learning about such an ubiquitous and important piece of machinery is quite satisfying. My curiosity is stoked primarily by interest in motor racing--when a book mentions 4-valve heads as an important aspect of engine development during the 1.5 liter F1 era, I want to know what that means. Alas, such knowledge doesn't keep me from fantasizing about racing a Lotus 33 at Spa, and degrading my own puny life experiences. Why aren't we satisfied with what we have?

@prashantjoshi9374 4 жыл бұрын

The intake valve is bigger than the exhaust valve because the pressure difference at the intake region is less (also mass flow rate less) than the pressure difference at the exhaust region(also mass flow rate more). But mass flow rates must be same for intake as well as exhaust (m(in) = m(out)) hence to satisfy this, the area of intake region should be bigger than the area of exhaust region.

Did you mention how the length of the valves effect the performance of the combustion intake? Did you mention the stem height? You need to explain this for clarity because if you order some valves and they are not the same lenght but the diameter is the same then you will have a combution problem balance in the intake gases and the exhaust gas also. Explain it please.
